Subject: [patch net-next v4 0/2] net: core: introduce mini_Qdisc and eliminate usage of tp->q for clsact fastpath

From: Jiri Pirko <jiri@...lanox.com>

This patchset's main patch is patch number 2. It carries the
description. Patch 1 is just a dependency.

---
v3->v4:
- rebased to be applicable on top of the current net-next
v2->v3:
- Using head change callback to replace miniq pointer every time tp head
  changes. This eliminates one rcu dereference and makes the claim "without
  added overhead" valid.
v1->v2:
- Use dev instead of skb->dev in sch_handle_egress as pointed out by Daniel
- Fixed synchronize_rcu_bh() in mini_qdisc_disable and commented

Jiri Pirko (2):
  net: sched: introduce chain_head_change callback
  net: core: introduce mini_Qdisc and eliminate usage of tp->q for
    clsact fastpath
